Minor NTP question ....

.... I have a RPiB+ on my LAN serving as the timekeeper for the LAN, running NetBSD-7 from a few weeks ago, working AOK. In my scenario, I am unhooked from the internet for periods of hours, always overnight, sometimes during the day as well. When I reconnect after these outages & look at 'ntpq -pn' output after a few min. when ntpd has redisvocered that the internet is back & goes back to syncing w/ my ISP, it is usually 6-10 sec. off. After a few hours, this is down to ~0.2 sec. or less, so all is well, however, I thought that when ntpd had settled in on a good drift value, it could coast for some time w/o getting too far off from its time source. I.e., I expect it to be maybe 1 sec. off after an outage, not 6-10 sec. Am I understanding things correctly ? Some data below:

rpi # ntpq -pn
remote refid st t when poll reach delay offset jitter
==============================================================================     .MSCF.           4 l 154m   64    0    0.000 0.000   0.000
*     3 u   34  256  377   16.222 -1.806   2.080
rpi # uname -a
NetBSD rpi 7.0_BETA NetBSD 7.0_BETA (RPI.201503272230Z) evbarm
rpi #

This is not a huge issue, since all LAN machines are kept well synced w/ the timekeeper & each-other, but it is curious (at least to me), so I'm asking. TIA & have a good one ....
